Today I was thinking... that, ok, we should waste less energy.. .that we should turn off lights when not using it and avoid putting electronics devices in stand by (the stand-by LED consumes energy).
But I was also thinking that we might as well get some help from the big companies. Building a cellphone (gps receiver, laptop, you-name-it device) charger that automatically powers itself off when not charging would definitely help. The same concept applies to other electronic devices as well (for example the TV).
That would help. A lot.
